Houston to Valparaiso

What the Data Says About IAH to VPS

The Houston to Valparaiso corridor (IAH → VPS) covers roughly 528 miles and is served by 5 carriers, based on Bureau of Transportation Statistics reporting. Across 912 flights in the dataset, this route posts a 86.2% on-time rate with an average delay of 76.6 minutes when flights run late. Over the most recent 24 months of BTS data, 912 flights were recorded on this pairing — 41 cancelled (4.5%) and 1 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 5 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 912 total flights analyzed, the 86.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 76.6-minute average delay applies only to flights that actually ran late, so it is not the average wait across all departures — the majority of flights on this route depart on time under the BTS definition of a delay (15+ minutes past schedule).

Looking at recent months, Mar 2020 posted the best performance on this corridor at 98% on-time, while Jul 2021 came in at 66% on-time — a 33-point gap between best and worst recent month. For travelers evaluating the IAH to VPS route, the combination of a 86.2% on-time rate, 76.6-minute average delay, 4.5% recent cancellation rate, and 5 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
